| 摘 要： | 由Peterson与Helfferich提出,经Conder和Purnell发展的色谱台阶脉冲法测定汽液平衡的方程经合理简化后被用于计算有限浓度汽液平衡.根据22组二元系(其中含极性组分者7组,含极性组分且部分互溶者3组,含聚合物组分者8组)的实验结果,推算值与实验值十分吻合,证明此方法可以应用.对吸附测定也作了探讨.

| Abstract: | The working equation of Conder and Young (1979) for the Chromatograph?ic Step-and-Pulse Method was reasonably simplified and used to predict vapour-liquid equilibria. Twenty-two binary systems including eleven miscible, three partially miscible and eight polymer containing systems were studied. The calculated solute activity coefficients and partial pressures were in good agreement with experimental data. Extension of this new equation to gas-solid adsorption isotherms was also studied. |
